A process for preparation of 2-(10,11-dihydro-10-oxodibenzo[b,f]thiepin-2-yl)propionic acid (i.e., Zaltoprofen) is performed by subjecting 2-(4-amino-3-carboxymethylphenyl)propionic acid or its salt to diazotization and subsequent reaction with thiophenol to produce 2-(3-carboxymethyl-4-phenylthiophenyl)propionic acid or its salt, and subjecting the product to cyclization reaction. Other related processes and related compounds are also disclosed.
